I want to answer a blase answer - 'yes of course you are!' but the honest answer is - I don't know.

I cant remember having a discharge while pregnant, especially at the beginning, no more than normal discharge anyway.

I do know that discharge changes texture throughout the month depending on what time of the cycle you are.

Doing a home pregnancy test and going to the doctors is the only way to know for sure

If your period is late, take a test. You can get one for $1 @ the dollar store.
